摘　　要：空间数据库是当前GIS技术的一个热点,GML已经成为空间数据编码、传输、存储、发布的国际标准,而KML也已经成为一个OGC标准。以GML/KML为基础构架空间数据库,解决了传统GIS空间数据库存在的诸多问题。通过比较空间数据库管理模式,分析采用GML/KML技术建立空间数据库的优点,着重探讨GML/KML技术构建空间数据库的框架。最后通过"数字九寨沟"实例进行验证,得出结论GML和KML是进行空间数据库设计的理想技术。Spatial database is currently a hot technology in GIS. GML has become the international standard for encoding, transmission,storage,and release of spatial data. KML has also become the de facto standard for OGC. GML/ KML infrastructure could solve many issues of traditional GIS spatial database. The construction of spatial database framework based on GML/KML is discussed. The different models of spatial database management are compared and the advantages of using GML/KML technology to establish spatial database is analyzed. As the final verification by an example of ＂digital Jiuzhaigou＂, we conclude that GML/KML is an ideal design technology for spatial database.
